ESCAPE-VALVE FOR STEAM-RADIATOBS.

Application filed. August 9, 1915.

1 b aZZ whom it may concern:

Be it known that I, ZACHARIAH T. Scorr, a citizen of the United States, residing at Canton, in the county of Fulton and State of Illinois, have invented certain new and 'useful innarovenaents in Escape-Valves for Steam-Radiators, of which the following is specification.-

improved escape valve for steam radiators and more particularly to a combined check and cut-oft valve: and the main object of the invention is to provide an improved valve that is automatically actuated and which will efiieotually control the water vithin the coils of the radiator and prevent the ]G- from overflowing.

. r -object of the invention is to proan improved valve of the above charv iich includes improved valve means ol the entrance of steam or water radiator and further, means to re movement of said valve means ill further obiect is to provide a dehe type in question that is extremely in. construction and which it is he my be manufactured at a comparanv cost.

ens other objects and advantages will become a varent during the continuance of the tollo description.

Thv and other objects which will become apparent accomplished by such .zneans are shown in their preferred form Wconipanying drawings, described in owing lcifica-tion and then more ny pointed out in the appended the accompanying drawings wherein 1 .0 like characters designate like parts throughout views, Figure 1 is a view of side 11 showing my invention attached to the elev

a code or the radiator. Fig". 2 is in verical section illustrating my ion in its preferred embodiment. tne accompanying drawings A designates a portion of an ordinary steam radiator in connection with which my invention has been illustrated. However it is to be under-e iod that my invention is not limited to any specific form of radiator whatsoever and. that the same may be advantageously used in connection with any of the practical forms.

In its preierred embodiment, my inven- Specification of Letters Patent.

' acent its ends is slightly constricted as at 13 and 14. The constricted portion 14 off. the interior bore of the body is interiorly screw threaded so as to receive a screw threaded portion 15 carried on the valve stem 16. The valve stem 16 is in turn provided with a pair of Winged extensions 17 by which its manipulation is greatly facili tated. it will be seen that by properly manipulating the valve stem 16 the head 18 thereof may be forced into the seat 19 so as to control the passage of steam or Water through the bore.

A collar 20 is carried upon the body portion 10, the inner periphery ,of the collar being screw threaded so as to receive the exteriorly screw threaded end of the casing 21. An opening 22 communicates with thev interior of the casing 21 and the enlarged portion 12 of the interior bore of the body 10 and in view of the fact that the casing 21 is also provided With a vent 23, it Will be appreciated that the air in the radiator can be forced outwardly therethrough.

closing the opening 22 and the vent 23 at certain times which is especiallydesirable in connection with a device of this character. To this end a float 24 is arranged within the casing 21 and is preferably of a diameter slightly smaller than the diameter of the casing. The lower flat face of the float 24 carries a nipple 25 which, when the float is in its normal position, projects into and closes the opening 22. A pin 26 is carried at the upper end of the float 24 and when the float is in the position in Fig. 2, remains out of engagement with the vent 23.

In Fig. 2 I have shown the body 10 provided with a cross rod 27 that projects into the constricted portion 1 of the interior bore and cotiperating with the enlargement l5 prevents the complete removal of the valve stem 16. r

Now, in the operation of this device when the same is attached to the radiator the parts will assume a position similar to that shown a 13 enters cilk; s

Having thus fully described. my invention, to secure by Letters Patent is in a valve of the character described, a body portion carrying a longitudinal bore, a valve stem adjustably mounted in said bore, a handle to actuate said valve stem, a

head at one endof said valve stein, a valve seat at one end of said bore to receive said head, a casing open at its lower end positioned on said body portion, said body provided with an opening communicating with said bore and said casing, one end of said casing being provided ZACHARIAH T. SCUTT.
